Cucumber and corn ( 2324 Â 3.00 , Â 0.13% ) The combination of the seed is mainly to take advantage of the high pole of corn. When the cucumber grows to the vine, it can be wrapped around the corn stalk, which can save a lot of fight costs and save production costs. It also improves the light, temperature, humidity and ventilation requirements of both crops. After the improvement, it is beneficial to the prevention and control of major diseases such as cucumber mosaic virus disease and downy mildew disease, and is more conducive to the prevention and control of corn size spot disease and corn aphid. I have carried out three years of trial planting in Da Nanmao: not only did the two crop intercropping not produce biological contradictions, but promoted each other, which increased the yield per unit area and output value of both crops by more than 30%. The current planting techniques are as follows:
First, choose the species. 1. Cucumber species choose Jintangqiu No.1 variety. The variety has early maturity, strong growth potential and good disease resistance. The plants have few branches and branches, and the main vines are melons. The melons are about 20-30 cm long and the diameter is about 4-6 cm. The color of the melon is white and green, the thorn is moderate, the quality is good, the meat is thick, the texture is crisp, and the taste is sweet. The average yield per mu is about 4,500 kg. 2, corn seed selection plant tall, root system developed, strong disease resistance, while having anti-falling varieties. Such as the Luo single series.
Second, fine land preparation. The land selection is preferably a field that can be irrigated, and the soil is sandy loam soil, which has the characteristics of good drainage. Use a rotary tiller to make the soil thin. Apply 3,000 kg of farmyard manure, 40 kg of phosphate fertilizer, 10 kg of potassium sulphate fertilizer, 0.2-0.5 kg of boron fertilizer and evenly mix the underground pests to make the base fertilizer. Snoring. Snoring is for good irrigation and management. Generally, the length of the snoring is 4-6 meters, and the width of the squat is 2 meters.
Third, sowing. First, the corn seeds are sown. The specifications are: the plant spacing is 50-60 cm; the row spacing is 80 cm. When sowing, it is best to pull the line live and the seeds are oriented, which is good for ventilation and light transmission. When the corn grows to 20 cm, the cucumber seeds can be sown. The sowing specifications are: the plant spacing is 50-60 cm; the row spacing is 90 cm. When planting cucumber seeds, it is 20-25 cm away from the root of the corn. After sowing, the seeds are covered with fine soil for 3-4 cm.
Fourth, field management. When the corn grows to 10-20 cm, it needs to be between the seedlings and the seedlings, and the weak seedlings are left. Two strong seedlings are left in each hole. If there is a lack of ponds, it is necessary to replenish the seedlings and pour the water to make up the seedlings. After the corn is to be revived, it is necessary to carry out a top dressing called “emergence of seedlingsâ€. After topdressing, we must carry out weeding and cover fertilizer to prevent loss of fertilizer efficiency. The management of cucumber is simple: first, the seedlings are crossed. We will weaken the seedlings, leave the seedlings strong, and hit the roots to leave the main vines, and use the rope to fix them on the main pole of the corn. Cucumber is a favorite fertilizer crop. It is necessary to topdress and water in time to prevent the occurrence of dead fruit. When the cucumber grows vigorously, the melon leaves will cover the ears of the corn, and the leaves are to be beaten so that the corn is better polled. Otherwise it will affect corn production.
5. Pest control. The use of interplanting techniques generally does not cause disease. If it does, use a low-toxic pesticide for bactericidal and insecticidal treatment.
Sixth, harvesting. Cucumbers are generally harvested from cucumbers, first harvested from the roots, and once every harvest, they are fertilized once, which is good for fruit. When the corn is harvested, it can be harvested when it is yellow.
